Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
How is the atomic mass of each element on the periodic table calculate?
The atomic mass listed on most periodic tables is actually the average atomic mass representing the average atomic masses of the various isotopes of an element depending on their percent natural abundance. Refer to the answers.com question: What is the formula for finding average atomic mass? for a detailed explanation on how to calculate this value.

How atomic mass is calculated?
It's the atomic number + the number of neutronsto find the average atomic mass you must multiply the mass by it's percent natural abundance. do that for each isotope and add your answers together
If the abundance of 85Rb is 72.2 and the abundance of 87Rb is 27.8 what is the average atomic mass of rubidium?
(85x72.2)+(87x27.8)= work it out.Divide the answer by 72.2+27.8Thats the answer
What is the average atomic mass compared to atomic mass?
Atomic mass is the number of protons and neutrons in an atom.
What is percent abundance?
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.

What is the automic mass of chlorine atom?
Chlorine 35: exact weight: 34.968852, percent abundance: 75.77 Chlorine 37: exact weight: 36.965903, percent abundance: 24.23 average atomic weight; 35.453
How percentage abundance is related to atomic number?
Percent abundance is not related to atomic number. Atomic number is the number of protons in the atomic nuclei of an element, and is unique to each element.
The average atomic mass of an element is the average of the atomic masses of its?
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.

What is the average atomic mass compared to the atomic mass?
Atomic Mass is the number of protons and neutrons in an atom.
How is the atomic mass for chlorine related to isotopes for that atom?
The average atomic mass is weighted by the most common isotopes and their relative abundance.
How is the atomic mass of an element affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
